Kuze kube manje, iningi lomdlavuza wesisu lomzimba, cishe 95%, linge-adenocarcinoma. Lesi sifo kunzima ukuyihlolisisa esiteji sokuqala, ngoba okokuqala kuvele kungenasifo. Ukuvela kwe-adenocarcinoma yesisu, abanye ochwepheshe bahlobanisa nokuba khona kukaHelicobacter pylori - ibhethri evunguza ehlala esiswini. Lesi sifo singazibonakalisa ngokumelene nesizinda se-gastritis, izilonda zesisu, ukwehlisa amandla okuzivikela. Ukungondleki okungalungile, nge-abundance of preservatives kanye ne-nitrites, kungabangela nokuba khona komdlavuza. Isici esivelele se-adenocarcinoma yesisu kubonakala kwe-metastases ekuqaleni kwesigaba.
Izinto ezine-adenocarcenoma
- ubudala kusukela eminyakeni 40-50;
- lesi sifo sithinteka kakhulu kubantu (izikhathi ezingu-2-3 kaningi kunabesifazane);
- ukuphuza utshwala nokubhema;
- ukutheleleka ngama-bacterium Helicobacter;
- ukudla ngokuchichima kasawoti, imikhiqizo yokubhema, izidakamizwa, ukudla okusheshayo;
- imvelo embi;
- ukulungiswa kwesintu.
Izimpawu zesifo
Njengoba kushiwo ngaphambili, isikhathi sokuqala se-adenocarcinoma yesisu sinamandla. Uma ukuxilongwa kutholakala ngesikhathi esifanele, khona-ke ukwelashwa okuphelele kungenzeka futhi ingozi yokucindezeleka incane kakhulu. Kodwa, ngeshwa, umdlavuza esiteshini se-zero utholakala ngengozi futhi kungavamile kakhulu. Ngokuhamba kwesikhathi, izimpawu ezilandelayo ziqala ukuvela:
- shintsha kokuncamelayo kokuncintisana nokuzwa;
- ukulahlekelwa isisindo kanye nokwanda okwesikhashana kwesibalo sesisu;
- ubuthakathaka ;
- ukuhlanzeka nokuhlanza;
- ubuhlungu besisu esifundeni sesisu;
- ukubonakala kwegazi esitokisini nokuhlanza esigabeni sokugcina sesifo.
Izinhlobo ze-adenocarcinoma
I-adenocarcinoma yesisu ngokusho kohlobo lwesakhiwo se-predominant component, njengoba umthetho, ihlukaniswe yaba izinhlobo ezimbili:
- I-adenocarcinoma ephakeme kakhulu yesisu (uhlobo lwamathumbu emdlavuza) - lunezakhiwo zompapa, izibulali noma i-cystic;
- I-adenocarcinoma engezansi ephansi yesisu (i-scirrus) - kunzima ukucacisa isakhiwo se-glandular, ngoba isisu sikhula ngaphakathi kwezindonga zelungu.
Kukhona into enjenge-adenocarcinoma ehlukene ngokwemvelo yesisu. Lezi zinhlobo zisezingeni eliphakathi phakathi kwezinga eliphezulu nokuphansi.
Ithuba lokubuyiselwa ngezinhlobo ezihlukene kakhulu zomdlavuza liphakeme kakhulu kunezinhlobo ezisezingeni eliphansi.
Ukwelashwa kwe-adenocarcinoma
Ukwelashwa okuyinhloko kwe-adenocarcinoma yesisu kuhlinzekwa, lapho isisu sisuswe khona ngokuphelele. Ama-lymph nodes angasuswa futhi. Ngemuva kokusebenza, i-radiotherapy ne- chemotherapy zixhunywe ngokungeziwe.
Ezimweni lapho ukungenelela okuhlinzekwayo kakade kungenzi umphumela oyifunayo, ukwelashwa kwesondlo kunqunywe. Kuzosiza ukudala induduzo enkulu kunayo yonke isiguli ngokunciphisa umsebenzi wezimpawu.
Isibikezelo sokuthola i-adenocarcinoma yesisu
Zixhomeke ezingeni lokulimala kanye nesigaba sesifo:
- Isigaba 1 - ukutakula ngo-60-80%;
- Isiteji sesi-2 - ukutakula 30-40%;
- Isigaba sesi-3 - ukutakula kwe-12-20%;
- Isiteji sesi-4 - ukutakula akukona kuka-5%.
Ukuthola lesi sifo, njengombuso, kwenzeka kakade
Izinyathelo zokuvimbela
Odokotela bayeluleka ukuba bahlolwe njalo ngezokwelapha futhi njalo eminyakeni engama-2-3 ukwenza i-gastroenteroscopy, ngisho noma kungekho izimpawu ezikhathazayo. Futhi, ukunakwa kukadokotela kufanele kuhilele ukuhlolwa kwegazi jikelele, lapho i-anemia noma ukwehla kwenombolo yamaseli obomvu ayenzeka.
